Levothyroxine And Fainting (Page 2)
(Newest replies first)

I was a perfectly healthy 14 year old until I grew very tired and went to see a doctor. We got blood work done & my tsh level was 150 (very bad) so my endocrine put me on 88mcg of levo. Im a little over a month into taking it and I've become very short of breath, having trouble excersising and today I fainted. I felt really nauseous and within 1 minute I passed out. Has anyone else experienced this?? I don't think it's normal but I'm curious if or how they fixed it. thanks

Yes. I experienced the same thing. I went off it (after discussing it w/Dr). It took several months for the bad feelings to go away and to quit passing out.

I've been on 100mcg once daily and never experienced any side effects at all that I've noticed except sweating profusely so if I was you I'd consult your doctor or pharmacist and explain to them what you're experiencing an let them know if it's anything to do with the levo or not. Hope you can get some answers and feel better
